Urm, sure it does - whether the xen kernel allows modules or not is just a KConfig setting. The XenSource kernel builds may not allow loadable modules but all Fedora Xen kernels are fully modular. You're right that VMware won't load/work, but that's a separate issue to the question of loadable module support in general. > The VMware modules really both need a) to run in ring0 (satisfied by your > suggestion) and to b) be supported by a full host Linux kernel. > Unfortunately, with Linux running in ring 1, whatever you do you are not > going to be able to satisfy both of these :-( Might be able to run VMware inside a HVM/fullyvirt guest.
